摘要

The invention describes a special apparatus that is placed in a Petri dish, or other type of dish, containing a liquid nutrient medium. The apparatus consists of a ring or frame that contains a fine porous mesh. A semi- permeable membrane is placed on the mesh with its lower surface in complete contact with the liquid nutrient medium. The cells of the various biological tissues, spores of fungi and yeasts, bacteria, algae, fungi and various other micro-organisms to be grown, are placed on the upper surface of the membrane where they draw up the diffused constituents of the nutrient liquid through the membrane.;f@οαοκοΉ @Y­Yαjο¶Yώ@Ήο@οώΟώϋx@ΉµΉϋοµx@ΚΎµ@¶ΎΚΎ®ο¶ο;¶Yώ@ο­¶ϊ @¶µλύ;Ύµ@Χ…£™‰@x@ ύύΎµ@ο;ΟΎµ @¶µλύ;Ύµ@ΚοώjΎ­¶Ύ @µνϊ@®οΚ¶ώϋϊ@µύώϋϊK@f@ΉµΉϋοµx@YΚΎ¶ούο;¶Yώ@YΚϊ@j­Y@ΟYϋ¶κύώΎ@x@ΚύY;ΉώΎ@ΚΎµ@Κοώjοώ@j­Y@ύοΚ¶ϊ@ΚΎΟο @ΚύjνYK@*Κ;@¶Ύµ@ΚύjνY¶Ύ @¶ΎΚΎ®ο¶ο;¶Yώ@ώY@ώΟώYΚοY¶x@ολ ­@ο@¶­@ϋ ¶½@οΚώα ­οώ @¶ @­Y@λ;Ήϋο¶Yώ@Ήο@Κύx@οΚYαx@ο@¶Ύ@µνϊ@®οΚ¶ώϋϊ@µύώϋϊK@s¶­@ ­½@οΚώα ­οώY@¶ @ολ ­ @¶ΎΚΎ®ο¶Ύκ­¶Yώ@νώY@Y­ Κ¶µΌ@ϋ궶YY@ΟώYαϊ½­@λώΎύΎνώϋ­@ώΉ¶­k@ΉΚϊώY@ᵶ­@x@µϋx¶½­k@λYϋ¶;ΟώYk@ακϋk@κϋ¶ο @ϋYώ@Οώ αΎΎώ@ ύύΎώ@ώϋΎΎνY­ώΉΎ;@ΚΎµ@Y­¶ύΎκ­@¶Y@ΟώYοϊο­Y@ΉµΉ¶Y¶ώϋ @¶Ύµ@®οΚ¶ώϋΎκ@µνΎκ@jΉ½@¶ @ολ ­ Kΰ
